This updated DisplayPort Dual-Mode Standard version 1.1 enables full support of HDMI 1.4 video modes, and 1080p deep color, using a simple cable adaptor plugged into the system's DisplayPort output.
An additional device, specifically a Dual-Mode DisplayPort cable adaptor, is required to convert the mechanical connector, as well as the electrical aspects of the signal, to output that is compatible with a DVI or HDMI cable and display.
Both editions feature re-tuned drivers touting better response for bass and cleaner output, along with a re-tooled approach to the quick disconnect cables and a new media cable with a revised inline remote and mic.
